an interesting piece of art, personally I am not known with the subject, so to me originality would be a 4.5, as an angel is not that original in my point of view.

The technique I must say deserves a 3.5, nice shading, it shows that the orb is emitting light, though it looks as if the wings should emit light as well, just like the glowing lines. If those intentionally aren't shaded like that, then please excuse me.

as for vision, well.. it shows the nice curves, though missing one arm and a lower legs, but that would most likely be part of the piece's purpose, to act to the impact, so it's a 4 for that.

and finally, a subject I personally find most important: Impact. This piece certainly has a nice impact at first sight, the gazing eyes staring into the orb, the glowing lines and wings, they all added up to the impact. The electrical surge (?) above her head gave the feeling as if she was being powered up, contributing to the title in comparison to impact, so a 4.5 for that.

all overall I can recommend this artist, sharing good pieces of art with the rest of dA.
